Walter Japan KK 具有冷卻孔的固鎢鋼鑽頭 DC1702008.731A1WJ30E DC1702008.731A1WJ30EJ DC1702008.731A1WJ30EJ

Feature

• By adopting a completely new margin design, we have ensured sufficient carbide base material at the key point, i.e., behind the cutting edge, exactly where the cutting resistance is acting, resulting in further stability and greatly improved productivity.
• The DC170 is reliable enough to withstand extreme mechanical conditions in the machining of sloped hole outlets or intersecting holes, effectively allowing cutting heat to escape from the tool along the rearward margin.
• A special margin arrangement minimizes unstable vibrations.
• This provides outstanding machining smoothness and unprecedented levels of process reliability for drilling.
• Work Material: Steel, Cast Iron
